Research Interests

I am interested Quaternary fossil pollen record, of south Africa and its palaeoenvirontal and palaeoclimatic implications. The results of fossil pollen analysis from different biomes in Southern Africa can be applied to reconstruct past vegetation patters, which in turn were influenced by climatic fluctuations. It is essential to obtain a closer grid of palaeo-environmental sites over the whole southern Africa to trace regional patterns of long-term climate change during the Quaternary and Neogene, and to understand our environmental system’s reaction to forces of global change. This will potentially provide us with a better insight of how prehistoric inhabitants had to cope under long-term environmental changes and what can be expected in terms of future climate changes.
